With the increasing demand of female friends for freckle removal, there are more and more freckle removal products on the market, especially many hormone products with the slogan of "three days effective, seven days freckle removal", which have attracted the attention of countless freckle removal people. So how should we choose these freckle products? How can I completely remove freckles on my face? Next, Bian Xiao takes you to explore freckle cheats.
What is the reason for the long spots?
1, congenital factor. Due to congenital genetic factors, some women's hormones contain more plaque matrix pigments than ordinary people, so such women are more likely to grow spots in the same environment.
2. Acquired factors. In the acquired environment, women's skin care is not in place, such as facing the computer for a long time, or the skin is directly exposed to the sun, which leads to ultraviolet damage to the skin and pigmentation of the facial skin. It may also be due to poor liver and gallbladder metabolism, gastrointestinal dysfunction or adrenal cortex dysfunction, leading to endocrine problems, affecting pigment metabolism and causing pigment deposition.
Whether it is to improve the current situation or prevent recurrence, sun protection is the most important part in the treatment of chloasma. Male patients should be encouraged to use broad-spectrum sunscreen (UVA and UVB) with SPF≥ 15, and sunscreen and other items.
2. External drugs
Many topical drugs are used to treat chloasma. These drugs can inhibit tyrosinase activity (hydroquinone, kojic acid, azelaic acid, arbutin, licorice extract, mulberry and raspberry) or prevent melanosome from being transported to keratinocytes (nicotinic acid, nicotinamide, soybean and retinoic acid) or accelerate the renewal of epidermal cells and reduce the time for epidermal cells to obtain melanin (α-hydroxy acid, β-hydroxy acid and retinoic acid).
Hydroquinone (HQ) and triple cream (HQ+ tretinoin [RA]+ corticosteroid [CS]) are still the gold standard of treatment, and then there are two combined therapies (HQ+RA, CS+RA, HQ+CS).
Local application of glucocorticoid may inhibit the biosynthesis and secretion of melanocytes, but its therapeutic mechanism has not been fully clarified. Triple cream local therapy is the first-line treatment for chloasma. Single drug therapy and combination therapy have low curative effect and slow onset, and can be recommended for patients who cannot accept combination therapy or are allergic to its components.
3. Chemical stripping agent
Different stripping agents can be used to improve and remove chloasma, including fruit acid, trichloroacetic acid, jessna solution, lactic acid, salicylic acid and retinoic acid. For patients with chloasma with dark skin, chemical exfoliating agents should be used with caution when applied externally. The use of surface exfoliating agents can avoid pigmentation after inflammation.
4. Oral tranexamic acid
Tranexamic acid (TA) is a synthetic derivative of lysine, which plays an anti-fibrinolytic role by blocking the lysine binding site on plasminogen molecules, and has been widely used as an anti-fibrinolytic and hemostatic drug. TA is an over-standard usage in the treatment of chloasma, which has been proved to be effective by a large number of clinical trials.
Prevent from being tanned
People with freckles must pay attention to sun protection. When you go out to play or work outdoors, you should take sun protection measures, such as wearing sunscreen, sun protection clothes, sun protection caps, etc., in order to reduce the damage of sunlight to the skin and avoid more freckles.
1, adding multivitamins.
2. Pay attention to eating habits
Drinking more water and eating more fruits and vegetables are of great significance for expelling toxins from the body. Keeping the stool unobstructed is very important for the care of chloasma! Because constipation is one of the chief culprits of toxin accumulation in the body!
Step 3 pay attention to sun protection
Ultraviolet rays, ionizing radiation, resolutely stay away! These things are the most important reason for the aggravation of chloasma! Because these things are an important reason to stimulate the activity of ammonia-cooling enzyme and lead to the "volcanic eruption" of pigmentation! This is well-known common sense. Therefore, women who are sensitive to ultraviolet rays should use sunscreen for a long time to prevent ultraviolet radiation. Stay away from serious environmental pollution and various harmful chemicals!
